The software used to determine LIP-tES feedback patterns was developed by Neurogen High Performance Neurofeedback. The EEG sampling frequency is 256 Hz on each of 2 EEG acquisition channels. The feedback LIP-tES is delivered via the 4 EEG leads (A+,A-,B+,B-), with respect to the Common Neck Reference. During each session, 2 electrodes (A- and B-) are attached to the participant's left and right mastoids, while the remaining two electrodes (A+ and B+) are moved to various locations on the scale to record EEG signals. All four (A+,A-,B+,B-) electrodes are involved in applying weak electrical pulses back to the brain (feedback process). The brief feedback pulse (\\~100mV) is adaptive and determined based on the offset of the frequency spectrum recorded across the left and right hemisphere (A vs. B) electrodes in the time window immediately prior to stimulation.",[9,15],[26],"LIP-tES intervention",[28],{"name":29,"affiliation":30,"role":31},"Francesca C Fortenbaugh, PhD","VA Boston Healthcare System Jamaica Plain Campus, Jamaica Plain, MA","PRINCIPAL_INVESTIGATOR",[33],{"name":29,"role":34,"phone":35,"phoneExt":36,"email":37},"CONTACT","(857) 364-4362",null,"Francesca.Fortenbaugh@va.gov",[39],{"facility":30,"status":40,"city":41,"state":42,"zip":43,"country":44,"cosmosGeoPoint":45,"geoPoint":50,"contacts":51},"RECRUITING","Boston","Massachusetts","02130-4817","United States",{"type":46,"coordinates":47},"Point",[48,49],-71.05977,42.35843,{"lat":49,"lon":48},[52,54],{"name":29,"role":34,"phone":53,"phoneExt":36,"email":37},"857-364-4362",{"name":29,"role":31,"phone":36,"phoneExt":36,"email":36},{"type":56,"investigatorFullName":36,"investigatorTitle":36,"investigatorAffiliation":36,"oldNameTitle":36,"oldOrganization":36},"SPONSOR","100524528",false,"NCT06109909","Pilot Study of Neurofeedback for Photosensitivity in Mild Traumatic Brain Injury","A Novel Neurofeedback Intervention for Photosensitivity in Mild Traumatic Brain Injury","Inclusion Criteria:\n\n* Ages 18-65\n* Documented history of mTBI at least 6 months prior to initial study visit\n* Documented symptoms of photosensitivity\n* Eye exam within the last 12 months documenting best-corrected acuity of 20\u002F20 or better, normal pupillary function, color vision, no abnormalities on OCT scan, and normal Humphrey Visual Field test\n\nExclusion Criteria:\n\n* History of strabismus or amblyopia\n* Significant ocular media opacity that could reduce the amount of light entering the pupil in one or both eyes\n* Previous or current history of retinal or optic nerve pathology in one or both eyes\n* History of stroke and\u002For visual neglect\n* History of neurodegenerative disease (e.g., Parkinson's, multiple sclerosis)\n* History of epilepsy or seizures\n* History of motor tics\n* Current use of medications or substances that may severely affect pupillary response and\u002For increase photosensitivity\n* Individuals with impaired decision-making capacity\n* Illiterate or no English language proficiency","ALL","18 Years","65 Years",{"count":67,"type":68},36,"ESTIMATED","INTERVENTIONAL",[71],"NA","The goal of this study is to complete a pilot study testing the feasibility and acceptability of low-intensity pulse-based transcranial stimulation (LIP-tES) neurofeedback intervention for reducing photosensitivity symptoms in Veterans with a history of mild traumatic brain injury (mTBI).
